JUST AIRCRAFT SUPER STOL XL OSHKOSH 2016 

Old tech- check Fiesler Storch from the Luftwaffe WWII...

blancolirio: Those were fixed slats. Add lots of drag at cruise but keep airflow attached at high angles of attack. Automatic slats are neat. Two sets per wing to keep functioning despite wing deflection. also the inner slats will collapse under high power settings from prop wash which is where you want the wing to stall . Still have 2/3 wing flying and have aileron control. At that power and AoA, the lift from the prop more than compensates.

The Messerschmitt 109 also had them.

I believe so, check with the folks at Just Aircraft...Harrison and Troy.

STOL fence- improved airflow over the elevator at low airspeeds.

+blancolirio yeah I saw the fence, but on the left stabilizer there seemed to be a mini flap at the end of it. I have never seen that.

+Landon Hillyard it's visible at 1:47

That's the elevator trim tab. Common to nearly all aircraft. Relieves the stick pressure at various airspeeds.

+blancolirio ah. thanks. learned something new today.
